The number should be 2.2250738585072012e-308
The number you have used is the one which affects PHP.

Precision in computing is important.

If your Java version is hit by the bug your code will hang the compiler.
If you want to compile the class and test the bytecode on different JVM
then use Double.parseDouble to parse a string constant. So far all these
versions I've tried are affected by this bug:

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_11-b06)
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
OpenJDK Client VM (build 14.0-b16, mixed mode) "1.6.0_17"
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode) "1.6.0_18"
